'MACHINE FOR ATTACHING TONGUES TO BUCKLES.

SPECIFICATION forming part of Letters Patent No. 410,770, dated September 10, 1889.

Application tiled April l2, 1889. Serial No. 307,008, (No model.)

To all whom it may concern:

Be it known that I, ADOLPH SAMsoN, a citiin Machines forAttachin g Ton gu es to Buckles,

of which the following is a specification.

This invention relates to a machine for attaching the pivoted tongues of buckles to the buckle-frame. Heretofore this has been accomplished by placing the tongue blank against the buckle-frame and bending the end of the tongue-blank around the cross-bar of the buckle by means of a reciprocating head or plunger. This method requires the buckle to be accurately located under the plunger and to be held by an attendant durinf; the bending operation, which consumes considerable time and renders the hands of the operator liable to be injured in centering and holding the buckles under the plunger.

The object of my invention is to construct a simple machine whereby the tongues are quickly attached to the buckle, so as to eect a saving in time and labor, and which requires no care or attention on the part of the operator other than to present the buckles and tongues to the machine.

The invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is Y a front elevation of my improved buckletonguing machine partly in section. Fig. 2-

is an end elevation thereof partly in section. Fig. 3 is a sectional elevatiomon an enlarged scale, of the compressing-die and one of the buckle carrying dies, showing the buckle frame and tongue in position ready to be united by the compressing-die. Fig. 4 is a similar view showing the tongue in the act of being bent or compressed. Fig. 5 is a top plan view of one of the carrying-dies.

Like letters of reference refer to like parts in the several figures.

Referring to Fig. 4,A represents the frame of an ordinary buckle, consisting of side bars and connecting end or cross bars, and b is the tongue, provided at its inner end with an eye, whereby it is attached to one of the cross-bars of the buckle-frame. Before being attached to the buckle-frame the tongue-blank is given the form shown in Fig. 3, its body having the shape of that of the finished tongue, with a hook-shaped portion c at one end, which is bent around the cross-bar of the buckle-frame to form the eye.

D represents the stationary frame of the machine, consisting of a horizontal bed and supporting-legs D', and D2 are two parallel standards secured to the bed and connected at their upper ends by a cross-piece d.

E represents a *revolving vertical disk arranged on one side of the machine and mounted on a horizontal shaft c, which is journaled in suitable bearings supported between the standards D2, one of these bearings being design ated by the letter e in Fig. 1, and the other is shown by dotted lines in the same ligure.

f represents the horizontal driving-shaft of the machine, having a driving-pulley f', and from which the'revolving disk Eis driven by a pinion f2, secured to said shaft and meshing with a gear-wheel F, formed on or secured to the rear side' of the disk.

G represents carrying-dies arranged at suitable intervals on the periphery of the rotating disk E, and which form traveling supports, upon which the buckle-frames, together with the tongues, are placed. These carrying-dies are provided with seats which are shaped to conform to and receive the buckleframe and tongue. The carrying-dies represented in the drawings are provided with a transverse recess g, for receiving the rear crossbar of the buckle-frame, to which the tongue is to be attached, and with a longitudinal recess or depression g', in which the tongue fits.

H represents an oscillating compressing-die arranged directly above the revolving disk E and journaled upon a horizontal arbor h, se-

. cured in the cross-piece d of the standards D2.

The compressing-die His provided on its under side with a curved recesso', which bends the projecting hook-shaped portion c of the tongue inwardly around the cross-bar of the buckle-frame, as represented .in Fig. 4, and thereby securely fastens the tongue to the buckle-frame. The bending-recess t is arranged in a longitudinal rib 5, formed at the lower portion of the compressing-die. The outer ends of the buckle-carrying dies G are recessed to receive this rib when the two dies come together, as clearly shown in Fig. et.

rlhe front advancing side of each carryingdie G is made straight and abrupt, as shown atj, and the compressing-die ll is provided with a corresponding abrupt face or shoulder r, which in the normal position of the compressing-die stands in the path of the abrupt iaces of the traveling dies G, so that the traveling dies will strike the shoulder of the compressing-die and swing the latter forwardly on its pivot, causing the bending-recess to act upon the tongue. As soon as a carrying-die has cleared the shoulder of the compressingdie, the latter is returned to its former position by a spring' l, attached at one end to the die and at its other end to the cross-piece (Z. The return movement of the compressing-die is limited by a projection m on the die, which strikes against a pin m', secured to the crosspiecc d, as represented in Fig. 3.

The buckle-frames to be tougued are placed face downward in the seats of the carryingdics on the ascending side of the revolving' disk E, with the free ends of the tongues resting against the front cross-bars of the buckleframes and the hooked portions of the tongues embracing the rear cross-bars of the buckleframe, as represented in Fig. The buckles and tongues are loosely held upon the carryin g-dics by the rear cross-bars of thebuckles, which lit in the transverse recesses (j of the dies. The carrying-dies in passing successively underneath t-he compressing-die turn the latter in the direction in which the travelin g dies move, thereby causing the bendingrecess 'i to approach the hook-shaped portions of the tongues and bending the same against the reareross-barof the buckle-trames. After the abrupt front side of a traveling-die has advanced out of contact with the shoulder of a compressing-die, as shown in Fig. 4, the swinging movement of the compressingdie is completed by the bent eye of the tongue bearing against the front side of the bendingrecess. As soon as the eye of the tongue clears the bending-recess, the springl returns the compressing-die to its original position ready to co-operate with the next succeeding carrying-die. On reaching the descending side of the revolving disk E, the tongued buckles fall out of the seats in the carrying-dies into a delivery-chute N, as shown in the drawings, or into a receptacle placed under the descending side of the disk.

By my improved machine the buckles are tongued at a single operation in a rapid and uniform manner without requiring manipulation of the buckles in proximity to the point at which the conipressing operation is cit'cctcd, thereby saving considerable time and labor and avoiding the liability of injury to the operator.

The arbor of the oscillating compressingdie ll is preferably arranged in a vertical slot n, formed in the cross-piece d,an d clamped therein by a nut applied to the inner screwthreaded end of the arbor, so that the die may be adjusted and the space between the compressing-die and the carrying-dies be varied to accommodate the thickness of the buckle to be tongued. The arbor is held against upward movement by a set-screw n', arranged in a threaded opening in the cross-bar (l.
